Nearsightedness (Myopia) Is Not a Life Sentence - Get Your Vision Back in Natural Ways
It is commonly believed that nearsightedness (myopia) is caused by over working our eyes at near distance objects for a lengthy period, such as reading, writing, stitching, working on the computer. By over doing our eyes in the above manner, the eye muscles are required to contract for a long period of time. In order to focus up close on these tasks, the eye muscles must contract for a length of time. Over time, the eyeball is slightly longer and flatter than the lens requires. As a result, light entering a myopic eye converges just before the retina (where the image is formed) and the resulting vision is blurred and out of focus.
Research shows that nearsightedness may not be determined by genetic factors alone, but habit, life style and the environment may also play a significant function.
Optometrists traditionally treat nearsightedness, with glasses or contact lenses, which do not cure the eye impairment, on the contrary it has been known that they may worsen the problem.
